Why do u belived the Indian Luzon came to shrine? what is his motive

Indian Luzon probably came to the shrine to rub it in Ramon's face and tell that his Father's fleet is gone because Indian luzon told Ramon a million times to throw back the Pearl and so luzon rub it in his face that he didnt do that and everything is now bad and hinting to Ramon that Manta Diablo wrecked the fleet. So Indian Luzon cam back to rub it in Ramon's face about the fate of the fleet and Father.

What do you belive happen to the sevillano in chapter 11? Mr. Salazar?

I belived that the fleet was wrecked and the Sevillano fell off and the Manta Diablo and the fish started attack and the Sevillano tried to fight back but they really attack him in the face which maybe explained the bloody face in Chapter 11. But they the fish flee because the manta diablo flee too. So then  the Sevillano tried to swim back which he and mutter the the Fleet is lost which it should be.

Manta Diablo differences Luzon and Ramon

  The difference in the way Soto
Luzon feels about the Manta Diablo and the way Ramon feels about the Manta Diablo is that since Ramon never saw the Manta Diablo and people keep sayign that it is vicous Ramon feels like it is a joke and thinks its beautiful since it was banished in the sea and Luzon must felt very afraid and no9t afraid because he made a pact with the Manta Diablo and afraid because Manta Diablo might as well vicous and is such a Beast!
   For example, Ramon feels that Manta Diablo is beautiful, in page 8 the first chapter, he never saw the Manta Diablo but when he was younger he thinks it was beautiful.  I wonder what does Manta Diablo looks like. I wonder if it is a Demon Giant!!
   For example, Soto Luzon is afraid of Manta Diablo, in page 37 chapter 6, Soto Luzon cannot go to the Manta Diablo's cave because he is AFRAID of the Manta Diablo and he made pact, a promise with Manta Diablo, so he cannot go in. I would keep the promise if I was Luzon but if I'm getting curious I would maybe go in like Ramon. Or just go near the cave.

    In conclusion, Soto Luzon feels afraid of the Manta diablo and also not afraid.  Ramon Feels that the manta Diablo is the most beautiful thing in the world and the sea!
